The closed tank of fig. p.2.34 is filled with water and is 5 ft long. the pressure gage on the tank reads 7 psi. determine: (a) the height, h, in the open water column, (b) the gage pressure acting on the bottom tank surface ab, and (c) the absolute pressure of the air in the top of the tank if the local atmospheric pressure is 14.7 ps

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

Argon, neon, and xenon are examples of
